    摘要： A dual valve prosthesis having first and second prosthetic valve sections is disclosed. The first prosthetic valve section includes a stent structure with a first prosthetic valve secured therein and the second prosthetic valve section includes an annular frame with a second prosthetic valve secured therein. When the dual valve prosthesis is in an expanded configuration, the annular frame extends from the stent structure such that the first and second prosthetic valves are laterally offset from each other. In a method in accordance herewith, the first and second prosthetic valve sections include prosthetic aortic and mitral valves, respectively, and the dual heart valve prosthesis is configured to replace both the native aortic and mitral valves of the heart in a single transcatheter heart valve implantation procedure.

    摘要： Heart valve delivery systems and methods of delivering and implanting heart valves using delivery catheters are disclosed. The delivery systems can include a handle assembly which can include a first control mechanism, a second control mechanism, and a decoupling mechanism. The delivery systems can also include a delivery catheter extending from the handle assembly. The delivery catheter can include an outer shaft, which can be controlled by the first control mechanism; a prosthesis containing capsule comprising a proximal capsule portion connected to the outer shaft, and a distal capsule portion releasably coupled to the proximal capsule portion. After deploying a valve prosthesis, the capsule can be closed by activating the decoupling mechanism in the handle to rapidly close the distal and proximal capsule portions together. The delivery system can also include a centering element to guide the distal and proximal capsule portions together.

    摘要： Valve introducer systems and methods for implanting heart valve prostheses are disclosed, where a valve introducer includes an adjustable deployment mechanism comprising a deployment element and an implantation depth controlling element having a distal end and an adjustable length. The valve introducer also includes a tubular member having a distal end, configured to deliver a heart valve prosthesis, and a length extending from a fixed reference point. The implantation depth controlling element can comprise an inner and an outer cylinder, such as where the outer cylinder has interior threads, and the inner cylinder has exterior threads. The adjustable deployment element can include a depth gauge, wherein the depth gauge indicates the length the tubular member extends beyond a fixed reference point. In certain embodiments, the adjustable deployment element can also be configured to be secured to a cannula.
